[0031] The automatic document storage and retrieval mechanism and document inspection device of the present application will now be described in detail with reference to the accompanying drawings.

[0032] Please refer to Figure 1 The automatic document storage and retrieval mechanism 100 provided in the embodiment of the present application includes a document bin 10 for placing documents, a top delivery assembly 20, a suction cup 30, a work station plate 40, a gripper 50, and a horizontal and vertical driving assembly 60 connecting the gripper 50.

[0033] Specifically, the document bin 10 can accommodate multiple documents and has a top opening 11 thereon. The top delivery assembly 20 includes a lifting plate 21 arranged above and below the document bin 10, a lifting rod 22 arranged on the lifting plate 21, and a top delivery driving assembly 23 connected to the lifting plate 21. The top delivery driving assembly 23 is used to drive the lifting plate 21 to move up and down relative to the document bin 10 to drive the lifting rod 22 to pass through the document bin 10 and lift all the documents in the document bin 10 to the top opening 11. The suction cup 30 is arranged above and below the document bin 10 and is arranged at the top opening 11. The work station tray 40 and the gripper 50 are arranged on the same side of the document bin 10. The horizontal and vertical driving assembly 60 is used to drive the gripper 50 to realize horizontal and vertical movements to drive the gripper 50 to clamp the document sucked by the suction cup 30 to the work station tray 40. The lateral movement is the forward and backward telescopic movement of the gripper 50 relative to the document bin 10 and the longitudinal movement is the up and down movement of the gripper 50 relative to the work station tray 40. It can be understood that the lateral movement and the longitudinal movement are perpendicular to each other.

[0034] like Figure 1 As shown, the top delivery drive assembly 23 includes a lifting guide plate 231, a motor 232 disposed on the lifting guide plate 231, a driving wheel 233 and a driven wheel 234 disposed on the lifting guide plate 231, and a synchronous belt 235 that drives and connects the driving wheel 233 and the driven wheel 234. The lifting plate 21 is fixedly connected to the synchronous belt 235 and slidably connected to the lifting guide plate 231. The lifting plate 21 moves up and down relative to the document compartment 10 on the lifting guide plate 231 during the movement of the synchronous belt 235.

[0035] Furthermore, the top delivery drive assembly 23 also includes a photoelectric baffle 236 fixedly disposed on the lifting plate 21 and moving with the lifting plate 21, and a top photoelectric switch 237 and a bottom photoelectric switch 238 both fixedly disposed on the lifting rod 22. The top photoelectric switch 237 and the bottom photoelectric switch 238 are arranged up and down on the moving path of the photoelectric baffle 236; the photoelectric baffle 236 moving with the lifting plate 21 is used to block the light beam emitted by the top photoelectric switch 237 or the bottom photoelectric switch 238.

[0036] It can be understood that the top photoelectric switch 237 and the bottom photoelectric switch 238 are arranged up and down on the moving path of the photoelectric baffle 236. The cooperation of the top photoelectric switch 237 and the photoelectric baffle 236 can be used to limit the detection of the lifting plate 21 moving upward to the highest position toward the document bin 10, and the cooperation of the bottom photoelectric switch 238 and the photoelectric baffle 236 is used to limit the detection of the lifting plate 21 moving downward to the lowest position away from the document bin 10. That is, when the photoelectric baffle 236 moving with the lifting plate 21 moves upward to block and reflect the light beam of the top photoelectric switch 237, the top photoelectric switch 237 generates a photoelectric signal, and the lifting plate 21 has reached the highest limit at this time, which means that the lifting rod 22 cannot rise at this time; similarly, when the photoelectric baffle 236 moving with the lifting plate 21 moves downward to block and reflect the light beam of the bottom photoelectric switch 238, the bottom photoelectric switch 238 generates a photoelectric signal, and the lifting plate 21 has descended to the lowest position at this time, which means that the lifting rod 22 will no longer continue to descend at this time, and the lifting rod 22 has descended to the lowest initial position.

[0037] Refer to Figure 2 and Figure 3 The transverse and longitudinal driving assembly 60 includes a transverse guide plate 61 arranged above and below the work station plate 40, a longitudinal guide plate 62 arranged perpendicular to the transverse guide plate 61 and capable of performing the transverse movement along the transverse guide plate 61, a robot arm 63 capable of performing the longitudinal movement along the longitudinal guide plate 62, a transverse driving device 64 arranged on the transverse guide plate 61 for driving the longitudinal guide plate 62 to move, and a longitudinal driving device 65 arranged on the longitudinal guide plate 62 for driving the robot arm 63 to move, wherein the aforementioned claw hand 50 is arranged on the robot arm 63.

[0038] In one embodiment of the application, the transverse driving device 64 and the longitudinal driving device 65 both include a motor, a driving wheel connected to the motor, a driven wheel, and a transmission belt that simultaneously transmits and connects the driving wheel and the driven wheel, wherein the longitudinal guide plate is connected to the transmission belt of the transverse driving device, and the robotic arm 63 is connected to the transmission belt of the longitudinal driving device 65.

[0039] Furthermore, the automatic document storage and retrieval mechanism 100 also includes a connection frame 70 that moves up and down with the work station plate 40 , the transverse guide plate 61 is arranged in the connection frame 70 and the suction cup 30 is connected to the connection frame 70 .

[0040] It is worth noting that the gripper 50 can move in the connection frame 70, with the side of the document bin 10 with the top opening 11 as the top surface, and the document bin 10 also includes a bottom surface arranged parallel to the top surface and multiple side surfaces connecting the top surface and the bottom surface, and the moving lifting rod penetrates the document bin 10 from the bottom surface parallel to the top surface of the document bin 10, and the station plate 40, the gripper 50 and the horizontal and vertical driving assembly 60 are all located on the same side of the document bin 10. In this way, the suction cup 30 sucks up the document at the top opening 11 above the top surface, and the horizontal and vertical driving assembly 60 drives the gripper 50 to move on the side of the document bin 10 to clamp the document sucked up by the suction cup 30.

[0041] Combined with reference Figure 1 and Figure 4 The document bin 10 includes a fixed box 12 and a collection bin 13 rotatably disposed in the fixed box 12. The top opening 11 and the side opening 14 are respectively provided on the adjacent two side walls of the fixed box 12, and the document entrance 131 and the document exit 132 are provided on the adjacent two side walls of the collection bin 13. During the rotation of the collection bin 13, the top opening 11 and the document exit 132 remain connected, and the document entrance 131 and the side opening 14 are connected or separated. Understandably, the document entrance 131 of the rotating collection bin 13 faces outward toward the user, and at this time, the document entrance 131 of the document bin 10 is connected to the side opening 14 of the fixed box 1242, and the user can put the document into the collection bin 13 from the connected document entrance 131 and side opening 14. Thereafter, the document entrance 131 and the side opening 14 of the collection bin 13 are rotated to be in a non-connected state, so that the document outlet 132 of the document bin 10 and the top opening 11 of the fixed box 12 are always kept connected during the rotation of the collection bin 13, so as to facilitate the evidence collection agency to collect evidence from the top of the document bin 10.

[0042] It is worth noting that, taking a passport as an example, one side of the document with the word "passport" written on it is generally the front side of the document, and the side opposite to the front side is the back side. The aforementioned side may include the open page side of the document that can be turned over, the hinge side that cannot be turned over, and the two side edges connecting the open page side and the hinge side. In terms of design, the size design of the fixed bin and the collection bin 13 of the document bin 10 is limited: when the user puts the document into the document bin 10, the document can only be put in in a closed state and in a longitudinal direction. The longitudinal placement is understood as: when the user faces the bin door, the open page side of the document is on the left or right side of the passenger or on the right hand side, that is, one of the side edges connecting the open page side and the hinge side faces the user. After the document is placed in the collection bin 13, the collection bin 13 rotates 90 degrees in the fixed box 12. At this time, the document in the collection bin 13 is in a horizontal placement state relative to when it was put in. The horizontal placement state is understood as: at this time, the open page side or the hinge side of the document faces the user.

[0043] Furthermore, the automatic document storage and retrieval mechanism 100 further includes a rotation drive device and a recognition camera 80; the rotation drive device is arranged on the mechanical arm 63 and connected to the gripper 50, and the recognition camera 80 is located on the gripper 50 and the collection surface faces the document bin 10. The rotation drive device may be, but is not limited to, a servo motor 232. The gripper 50 is an electric gripper, which is a standard part controlled by the servo motor 232 to close and open the gripper.

[0044] It is worth noting that since the suction cup 30 sucks up the document from one side of the document, the open side of the document spreads out under the action of gravity, so in order for the claw hand 50 to grasp the document more smoothly, the hinge side of the document needs to face the claw hand 50. However, as mentioned above, although the document is placed vertically and the collection bin 13 rotates 90 degrees, the document is then kept horizontally to wait for the suction cup 30 to suck the document, but since the hinge side has two different directions when the user places it vertically, it is difficult to ensure that the hinge side of the collection bin 13 must face the claw hand 5023 after the rotation. In order to solve this problem, the cooperation of the aforementioned recognition camera 80 is required, specifically: when the claw hand 50 does not grab the document, the mechanical arm 63 provided with the claw hand 50 is in the initial position, and the mechanical arm 63 is spatially opposite to the top opening 11 located at the top of the document bin 10. When the suction cup 30 sucks up the top document in the document bin 10, the side view of the side of the document is collected by the first camera, and the first camera identifies whether the side in the side view is the hinge side through the target detection model. Among them, the target detection model can be identified by the existing YOLOX learning model, and the aforementioned target detection model is obtained by collecting the data image of the hinge side of the document and the scattered data image of the open page side of the document for model training. When the target detection model identifies that the side in the side view belongs to the hinge side of the document, the collection bin 13 does not rotate. When the target detection model identifies that the side in the side view belongs to the open page side of the document, the collection bin 13 is driven by the motor 232 to rotate 180 degrees so that the hinge side faces the claw hand 50.

[0045] Please refer to Figure 3The document inspection device 200 provided in the embodiment of the present application also includes a frame 201, a three-dimensional guide rail 202 arranged on the frame 201, the aforementioned stamping machine 206, the document automatic storage and retrieval mechanism 100, a page turning machine 203, a document scanner 204, a labeling machine 205 and a stamping machine 206. Among them, the automatic document storage and retrieval mechanism 100 and the three-dimensional guide rail 202 are arranged on the frame 201, and the work station tray 40 of the automatic document storage and retrieval mechanism 100 slides along the work station tray 40; the page turner 203, the document scanner 204, the labeling machine 205 and the stamping machine 206 are arranged at intervals on the frame 201 and distributed along the sliding path of the work station tray 40; the document clamped by the claw hand 50 and placed on the work station tray 40 moves to the page turner 203 for page turning, moves to the document scanner 204 for document recognition, moves to the labeling machine 205 for labeling, and moves to the stamping machine 206 for stamping as the work station tray 40 slides on the frame 201.

[0046] It is worth noting that the page turner 203 is a device for turning pages of documents, for example, the page turner 203 can be but not limited to the automatic page turner with the publication number CN1562642A, the automatic page turner 203 can turn pages in both positive and negative directions, the document scanner 204 is an existing machine that can realize OCR text recognition and image recognition, the stamping machine 206 is a device for automatically stamping documents, and the labeling machine 205 is a label printing and labeling machine, the page turner 203, the document scanner 204, the stamping machine 206 and the labeling machine 205 can be any existing device, which will not be repeated here. The operating equipment such as the page turner 203, the document scanner 204, the stamping machine 206 and the labeling machine 205 can be set on the sliding rod, and the aforementioned equipment can move relative to the support assembly 40 transmitted, so that each operating equipment is close to the document on the support assembly 40, and at this time the support assembly 40 acts as a plate for placing the document of each operating equipment. Among them, the labeling machine 205 is a device for printing labels. Visa labels need to be pasted during customs clearance. The labeling machine 205 is a device for printing and pasting visa labels, and any labeling machine in the prior art can achieve this.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
